  FIG. 9 is a diagram illustrating a hardware configuration example of the score input device according to the embodiment of the present invention. The score input device is, for example, a personal computer.

  A central processing unit (CPU) 902, a ROM 903, a RAM 904, a network interface 905, an input device 906, an output device 907, an external storage device 908, and a sound source 909 are connected to the bus 901.

  The CPU 902 performs data processing or calculation and controls various components connected via the bus 901. The ROM 903 stores a control procedure (computer program) of the CPU 902 in advance, and is activated when the CPU 902 executes the computer program. A computer program is stored in the external storage device 908, and the computer program is copied to the RAM 904 and executed. The RAM 904 is used as a work memory for inputting / outputting data and a temporary storage for controlling each component. The external storage device 908 is, for example, a hard disk storage device or a CD-ROM, and the stored content does not disappear even when the power is turned off. The CPU 902 executes the computer program in the RAM 904, thereby performing the processing of the flowcharts of FIGS. 4 to 8 to be described later, and displays the windows shown in FIGS.

  The network interface 905 is an interface for connecting to a network. The input device 906 is, for example, a keyboard and a mouse, and can perform various designations or inputs. The output device 907 is a display (display device), a printer, a speaker, and the like. The sound source 909 generates a tone signal based on the picture score data and / or score data and causes the speaker 907 to generate a sound.

  As described above, by executing the score creation software or score performance software using a personal computer or the like, the pictorial score and the score of FIGS. 1 to 3 can be displayed on the output device 907 or printed. it can.

  FIG. 1 is a diagram showing a window displayed on the display 907. The CPU 902 displays a picture score 121, a score 122, a symbol (note and rest) button 101, and operation buttons 111 to 117 in a window. A picture score 121 and a score 122 corresponding to the picture score 121 are displayed. A pictorial score is a pictorial representation of a score. In the picture score 121, notes 201-204 of “DO”, “RE”, “MI”, “FOO” are displayed pictorially. The height of the note is indicated by the letters “DO”, “RE”, “MI”, “FOO” and the vertical position. The length of the note is indicated by the width. The CPU 902 displays the picture score 121 based on the picture score data in the external storage device 908. As the score 122, only the staff score is displayed in the initial stage.

  The child first learns the picture score, and then learns the score. A user such as a child can learn a musical score by inputting a note corresponding to the musical score 121 onto the musical score 122 using the symbol button 101 while watching the musical score 121. The symbol button 101 includes a 2nd note button, a 4th note button, an 8th note button, a 2nd rest button, a 4th rest button, an 8th rest button, and a dotted button. The user designates the type of note or rest (length of note or rest) by clicking a predetermined button in the symbol button 101 with the mouse 906, and clicks the mouse 906 on the staff of the score 122. Use to specify the position of the note or rest. The length of the sound is specified by a button in the symbol button 101, and the pitch of the sound is specified by a click position on the staff score 122.

  The buttons 111 to 117 can be instructed when the user clicks with the mouse 906. The open button 117 is a button for opening the file and displaying the picture score 121 or the score 122. The picture score button 111 is a button for instructing whether or not the picture score 121 is to be played. The score button 112 is a button for instructing whether or not the score 122 is to be played. The start button 114 is a button for starting the performance of the target musical score 121 and / or the musical score 122 designated by the musical score button 111 or the musical score button 112. The timbre to be played can be set for each of the picture score 121 and the score 122. The timbre includes floor chanting. The floor name singing is a timbre that produces a floor name such as “do”, “le”, “mi”, and the like. For example, if both the musical score 121 and the musical score 122 are played simultaneously, it is possible to easily grasp whether or not the inputted musical score 122 matches the pictorial score 121. The stop (stop) button 113 is a button for stopping the performance started by the start button 114.

  The mistake button 115 is a button for pointing out and displaying a place where the inputted score 122 is wrong. The hint button 116 is a button for displaying a hint for inputting the musical score 122, and displays, for example, a sound length (note type) or a sound pitch (position on the staff) as a hint.

  FIG. 2 is a diagram showing an input example of correct notes 211 to 214 of the score 122, and shows a part of the window of FIG. In the initial state of FIG. 1, the notes 201 to 204 of the picture 121 are displayed, and the notes of the score 122 are not displayed. The user inputs the same note as the picture score 121 on the score 122 while watching the picture score 121. Then, as shown in FIG. 2, the inputted notes 211 to 214 on the score 122 are displayed. If the hint button 116 is pressed, floor names are also displayed on the notes 211 to 214. The notes 211 to 214 of the score 122 are correctly input corresponding to the notes 201 to 204 of the picture score 121, respectively. By displaying the pictorial score 121 and the musical score 122 side by side, it is possible to input notes and the like of the musical score 122 while viewing the pictorial score 121, and to easily compare the pictorial score 121 and the musical score 122. Further, by comparing the picture score 121 and the score 122, the length and pitch of the sound can be visually understood, which is useful for learning the score 122.

  FIG. 3 is a diagram showing an input example of wrong notes 301 to 304 of the score 122, and shows a part of the window of FIG. The notes 301 to 304 of the score 122 are erroneously input to the notes 201 to 214 of the picture 121, respectively.

  The correct pitch of the note 301 is “do”, but the wrong pitch “si” is input, so “x” is displayed on the note 301. Also, an up arrow (“↑”) 311 is displayed to the right of the note 301 to notify that the pitch of the input note 301 is too low.

  The correct pitch of the note 302 is “L”, but the wrong pitch “M” is input, so “×” is displayed on the note 302. Also, a down arrow (“↓”) 312 is displayed to the right of the note 302 to notify that the pitch of the input note 302 is too high.

  The correct length of the note 303 is a quarter note, but since a half note has been input by mistake, “x” is displayed on the note 303. Further, an inner arrow (“→ ←”) 313 is displayed above the note 303 to notify that the input note 303 is too long.

  The note 304 has a correct length of a half note, but a quarter note has been input by mistake, so “×” is displayed on the note 304. Further, an outer arrow (“← →”) 314 is displayed above the note 304 to notify that the length of the input note 304 is too short.

  In the 4/4 time signature, since the total length of the first measure 321 is too long, the first measure 321 is displayed in red as a check result. In addition, since the total length of the notes in the second measure 322 is too short, the second measure 322 is displayed in blue as the check result.

  FIG. 4 is a flowchart showing the score input method of the score input apparatus according to the present embodiment. First, in step S401, when the input device 906 instructs the start of the score input software (program) by the user's operation, the CPU 902 starts the score input software and performs the following processing.

  Next, in step S402, the CPU 902 performs initialization processing. Specifically, initialization processing for sound source initialization and display for producing sound is performed.

  Next, in step S403, the CPU 902 displays the window of FIG.

  Next, in step S404, the CPU 902 detects an operation of the input device 906 such as a mouse and a keyboard.

  Next, in step S <b> 405, the CPU 902 performs processing when the input device 906 is operated. Details thereof will be described later with reference to FIG.

  Next, in step S <b> 406, the CPU 902 performs display processing because the state changes depending on the processing. Details thereof will be described later with reference to FIG. Then, it returns to step S404 and repeats said process.

  FIG. 5 is a flowchart showing details of processing related to the operation in step S405 of FIG. First, in step S501, the CPU 902 checks whether or not the open button 117 has been pressed (clicked with the mouse). If it has been pressed, the process proceeds to step S502, and if not, the process proceeds to step S503. In step S502, the CPU 902 performs processing of the open button 117. For example, the designated file is opened and the picture score 121 or the score 122 is displayed. Thereafter, the process ends.

  In step S503, the CPU 902 checks whether or not the quarter note button in the symbol button 101 has been pressed. If it is pressed, the process proceeds to step S504, and if it is not pressed, the process proceeds to step S505. In step S504, the CPU 902 performs a quarter note button process. For example, a quarter note is displayed at a specified pitch position on the staff of the score 122 in response to a click operation on the score 122 by the user's mouse 906, and quarter note data is generated on the RAM 904. Thereafter, the process ends. Similarly to the quarter note button, the same processing is performed for the other buttons in the symbol button 101.

  In step S505, the CPU 902 checks whether the wrong button 115 has been pressed. If it is pressed, the process proceeds to step S506, and if it is not pressed, the process proceeds to step S507. In step S506, the CPU 902 performs processing of the error button 115. For example, the error display mode is set or not set. Thereafter, the process ends.

  In step S507, the CPU 902 checks whether the start button 114 has been pressed. If it has been pressed, the process proceeds to step S508, and if not, the process proceeds to step S509. In step S508, the CPU 902 performs processing of the start button 114. For example, control is performed to cause the sound source 909 to play the target musical score 121 and / or score 122 instructed by the picture score button 111 or the score button 112. Thereafter, the process ends.

  In step S509, the CPU 902 checks whether the stop button 113 has been pressed. If it is pressed, the process proceeds to step S510, and if it is not pressed, the process proceeds to step S511. In step S510, the CPU 902 performs processing of the stop button 113. For example, the performance of the picture score 121 and / or the score 122 is stopped. Thereafter, the process ends.

  In step S511, the CPU 902 checks whether the picture score button 111 has been pressed. If it has been pressed, the process proceeds to step S512, and if not, the process proceeds to step S513. In step S512, the CPU 902 performs processing of the picture score button 111. For example, the performance target or non-target of the picture score 121 is set by a toggle button. When the picture button 121 is pressed and the start button 114 is pressed after the picture score 121 is set as a performance target, the sound of the picture score 121 is sounded. Thereafter, the process ends.

  In step S513, the CPU 902 checks whether or not the score button 112 has been pressed. If it has been pressed, the process proceeds to step S514. If not, the process proceeds to step S515. In step S514, the CPU 902 performs processing of the score button 112. For example, an object to be played or non-object for the score 122 is set by a toggle button. When the score button 112 is pressed and the score 122 is set as a performance target, and the start button 114 is pressed, the score 122 sounds. If both the picture score 121 and the score 122 are sounded at the same time, it is possible to confirm the mistakes in the notes and rests that have been heard on the ear and entered on the score 122. Thereafter, the process ends.

  In step S515, the CPU 902 performs other processing. For example, the hint button 116 is processed. Thereafter, the process ends.

  FIG. 6 is a flowchart showing details of the display process in step S406 of FIG. First, in step S601, the CPU 902 checks whether or not the error display mode (step S506 in FIG. 5). If it is the error display mode, the process proceeds to step S602, and if it is not the error display mode, the process proceeds to step S603.

  In step S <b> 602, the CPU 902 displays whether the notes or rests in the measure of the input score 122 are excessive or insufficient. Details thereof will be described later with reference to FIG. Thereafter, the process proceeds to step S603.

  In step S <b> 603, the CPU 902 displays a normal score 122. For example, the notes 211 to 214 (FIG. 2) or rests input on the score 122 are displayed.

  Next, in step S604, the CPU 902 checks whether or not the error display mode (step S506 in FIG. 5). If it is the error display mode, the process proceeds to step S605, and if it is not the error display mode, the process is terminated.

  In step S <b> 605, the CPU 902 displays the correct answer (◯) or incorrect answer (×) of the note or rest on the input score 122. Details thereof will be described later with reference to FIG. Thereafter, the process ends.

  FIG. 7 is a flowchart showing details of the display processing of excess / deficiency in the measure in step S602 of FIG. The following processing is performed for each measure.

  First, in step S701, the CPU 902 obtains a total A of the lengths of the notes in the bar, with the quarter note being 48 in length. Next, in step S702, the CPU 902 obtains the time signature H × 48 of the music as the reference K. The reference K is 192 for quadruple time.

  Next, in step S703, the CPU 902 checks whether the total length A is smaller than the reference K. If it is smaller, the process proceeds to step S704, and if not smaller, the process proceeds to step S705. In step S704, the CPU 902 fills the background of the bar with blue, and informs that the total length of the notes in the bar is too short. For example, the background of the second bar 322 in FIG. 3 is painted in blue. Thereafter, the process ends.

  Next, in step S705, the CPU 902 checks whether or not the total length A is larger than the reference K. If it is larger, the process proceeds to step S706, and if it is not larger, the process is terminated. In step S706, the CPU 902 fills the background of the bar with red and informs that the total length of the notes in the bar is too long. For example, the background of the first bar 321 in FIG. 3 is painted in red. Thereafter, the process ends. The above processing is performed for all measures.

  FIG. 8 is a flowchart showing details of the XX display process for each sound in step S605 of FIG. The following processing is performed for the J-th symbol (note or rest) of the I measure of the score 122.

  First, in step S <b> 801, the CPU 902 checks whether or not there is a J-th symbol of the I bar of the musical score 121 corresponding to the J-th symbol of the I bar of the score 122. If there is a symbol, the process proceeds to step S803, and if there is no symbol, the process proceeds to step S802. In step S <b> 802, the CPU 902 displays “X” in the J-th symbol of the I measure of the score 122 to notify that it is an erroneous extra symbol. Thereafter, the process ends.

  In step S <b> 803, the CPU 902 checks whether or not the J-th symbol of the I bar of the score 122 is the same type (note / rest) as the J-th symbol of the I bar of the picture score 121. If they are the same, the process proceeds to step S805; otherwise, the process proceeds to step S804. In step S <b> 804, the CPU 902 displays “x” in the J-th symbol of the I measure of the score 122 to notify that the symbol is the wrong type. Thereafter, the process ends.

  In step S <b> 805, the CPU 902 checks whether the J-th symbol of the I bar of the score 122 is the same length as the J-th symbol of the I bar of the picture score 121. If they are the same, the process proceeds to step S810; otherwise, the process proceeds to step S806. In step S806, the CPU 902 displays “x” in the J-th symbol of the I measure of the score 122 to notify that the symbol has the wrong length. For example, “x” is displayed on the notes 303 and 304 in FIG. Thereafter, the process proceeds to step S807.

  In step S <b> 807, the CPU 902 checks whether the length of the Jth symbol of the I bar of the score 122 is longer than the length of the Jth symbol of the I bar of the picture score 121. If longer, the process proceeds to step S808, and if shorter, the process proceeds to step S809. In step S808, the CPU 902 displays “→ ←” above the J-th symbol of the I measure of the score 122. For example, an inner arrow (“→ ←”) 313 is displayed above the note 303 in FIG. 3 to inform the user that the symbol is too long and should be corrected. Thereafter, the process ends. In step S 809, the CPU 902 displays “← →” above the J-th symbol of the I measure of the score 122. For example, an outer arrow (“← →”) 314 is displayed above the note 304 in FIG. 3 to inform the user that the symbol should be corrected longer because it is too short. Thereafter, the process ends.

  In step S <b> 810, the CPU 902 checks whether the J-th symbol (note) of the I bar of the score 122 is the same height as the J-th symbol of the I bar of the picture 121. If they are the same, the process ends. If not, the process proceeds to step S811. In step S811, the CPU 902 displays “x” in the J-th symbol of the I measure of the score 122 to inform that the symbol has the wrong height. For example, “x” is displayed on the notes 301 and 302 in FIG. Thereafter, the process proceeds to step S812.

  In step S 812, the CPU 902 checks whether the height of the J-th symbol (note) of the I bar of the score 122 is higher than the height of the J-th symbol of the I bar of the picture score 121. If it is higher, the process proceeds to step S813, and if it is lower, the process proceeds to step S814. In step S813, the CPU 902 displays “↓” to the right of the J-th symbol in the I measure of the score 122. For example, a down arrow (“↓”) 312 is displayed to the right of the note 302 in FIG. Thereafter, the process ends. In step S <b> 814, the CPU 902 displays “↑” to the right of the J-th symbol in the I measure of the score 122. For example, an up arrow (“↑”) 311 is displayed to the right of the note 301 in FIG. Thereafter, the process ends.

  The above processing is performed for all symbols (notes and rests) of all measures. In this example, an instruction to lead to a correct answer (“← →” in the sense of “longer”) is displayed, but a display indicating a state (“← →” because it is longer than the reference) may be displayed. Further, in this example, the correct answer is not particularly displayed, but “◯” may be displayed as the correct answer symbol.

  In addition, although the case where it complete | finishes after step S808 and S809 was demonstrated, you may perform the process of step S810 continuously. In this case, both the length display (“← →” or “← →”) and the height display (“↓” or “↑”) are displayed.

  As described above, it is possible to display an error in the symbol of the score 122 inputted by the user. It displays errors in the length of the symbols (notes and rests) and the height of the notes, as well as how to correct them, so the user can know how to correct the wrong symbols, Useful for learning.

  The score input apparatus according to the present embodiment displays a pictorial score 121 that represents the pitch and length of the sound with pictorial symbols, and displays a staff score of the score 122 corresponding to the pictorial score 121 on the display 907. And input means for inputting symbols (notes or rests) of the score 122 in response to an input instruction using the mouse 906. The display means and the input means correspond to the processing of the CPU 902. The display means displays the input symbols 211 to 214 on the musical score 122.

  The display means displays when the symbol of the inputted score 122 is incorrect with respect to the symbol of the picture score 121 corresponding thereto. For example, “x” is displayed on the notes 301 to 304 in FIG. 3 or arrows 311 to 314 are displayed.

  Further, corresponding to steps S805 to S809 in FIG. 8, the display means makes the length of the input musical score or rest incorrect relative to the corresponding musical note or rest length. If so, this is displayed. For example, “x” is displayed on the notes 303 and 304 in FIG. 3, and arrows 313 and 314 are displayed.

  Specifically, when the length of a note or rest of the input score is wrong with respect to the length of a note or rest of the picture score corresponding thereto, the display means inputs the input score. It is displayed that the length of the musical note or rest is too long or too short relative to the corresponding musical note or rest. In FIG. 3, an arrow 313 is displayed when it is too long, and an arrow 314 is displayed when it is too short.

  Further, corresponding to steps S810 to S814 in FIG. 8, the display means indicates that the note height of the inputted score is wrong with respect to the corresponding note height of the picture score. indicate. For example, “x” is displayed on the notes 301 and 302 in FIG. 3, and arrows 311 and 312 are displayed.

  Specifically, the display means, when a note height of the input score is wrong with respect to a corresponding note height of the pictorial score, the note height of the input score. Indicates that it is too high or too low relative to the height of the corresponding musical note. In FIG. 3, an arrow 312 is displayed when it is too high, and an arrow 311 is displayed when it is too short.

  Corresponding to the processing of FIG. 7, the display means displays that when the total length of the notes in one measure of the input score is wrong with respect to the time signature of the music.

  Specifically, when the sum of the lengths of the notes in one measure of the input score is wrong with respect to the time signature of the song, the display means displays the notes in the measure of the input score. The fact that the total length is too long or too short for the time signature of the song is displayed. In FIG. 3, since the total length of the notes in the first measure 321 is too long, the background of the measure is painted in red, and the total length of the notes in the second measure 322 is too short. Fill the background of the bar with blue.

  Further, corresponding to the processing of step S508 in FIG. 5, the performance means plays the picture score 121 and / or the score 122 using the sound source 909 and the speaker 907. The performance means corresponds to the processing of the CPU 902.
